What to do with those offsets? Why are they there? Is it like the controller thinks it is rotated but the copter is not? Is it because we start at a slightly leaning ground?
Flight controller is in the center of the multicopter, Pixhawk is level, it is also level-calibrated in MP. With artificial horizon, do you mean “the green ground” in the hud in MP? It is level when the multicopter is level. Trims are 0 0 0 0.
ESCs are calibrated using Mission Planners own function. It is useless in informing what is going on and when it is done. The controller beeps, all motors beeps. How dou you know is was successful? The multicopter flies very well though.
If we put the multicopter on a slightly leaning ground, not much, and then arms it, the motors idle normally. Then we give very little throttle and the motors revs upp very high instantly. The motor on the lowest arm revs up more than the others. The more down the arms are, the more their motors revs up. Why doesnt it rev up softly from 0-50 if we do this in for example 2 seconds? What is the point of jumping up to almost liftoff?
Log-file from a short flying from asphalt with a jumpy start (it “vibrates” some in the start), then flies good.
